The Stability of The Solar System - Scott Tremaine

This is exactly what I was looking for. Thanks for the video.

this is a great video

Excellent Prof. Tremaine, but it is not mentioned that the French astronomer J. Laskar discovered the chaoticity of the solar system, especifically, the instability of Mercury, in shorter timescales, say, about 5 Myr from now...

Fascinating.

[@JonasWeezer]

Has anyone considered the magnetic fields of planets and the Sun contributing to the stability of the orbits at least in our solar system?

[@chiragadwani1875]

Generally speaking, the electromagnetic forces occupy a very different energy scale than gravitational forces. While the effect that you question will be non-zero and may grow exponentially due to the chaotic nature of the solar system, it’s still going to be fairly insignificant compared to direct gravitational effects. That being said, there are astronomical bodies, namely neutron stars, that have a powerful enough magnetic fields that affects their own structures!

Fuzzy logic allows a finite range of tolerance to allow the stability of the solar system.

according to newton every particle attaches to the earth due to gravity .but why the planets of low gravity (mars ,earth .saturn,uranus,neptune,pluto etc are not attracted to the sun,as sun gravity is more than other planets.

What the hell are you talking about? Of course they are attracted to the sun that's why they orbit around the sun and not around a planet. Furthermore, this applies to galaxies as well. Most, if not all galaxies have a black hole at the center. And just like planets orbiting around the sun, solar systems orbit around black holes. The Milky Way Galaxy which our system belongs to has a super massive black hole known as Sagittarius A appears to be at the exact center.

So, no. every planet in our solar system is attracted to the sun. their gravities are pulling the sun towards their center and the suns gravity is pulling the planets to the sun center. the planets dont have 'low gravity', but relative to the sun then yes. we orbit the sun because we are attracted to the sun. not sure where you learned what you commented but its not right. hope this helps! :)

Are you having a stroke?
